Hi,
I was trying out some examples of using multi_index_container with custom allocator. I found out that even an empty container, on creation, allocates memory for a single node (but no element is stored inside).
In other words, if I store N elements, the container allocates memory for N+1 elements.

Is it a fault?
If not, what is this memory used for?
Is there any way to avoid this allocation?

Regards,
Jakub
